Integrate Wefido Signals

A consistent format for measuring browser, WordPress and server-side events, with consent management and deduplication.

Web SDK

Script for custom websites

Create a source, verify its domain and use only the public Web Signal key.

<script
  src="https://wefido.it/sdk/wefido-signals.js"
  data-wefido-source-key="wfs_web_..."
  data-wefido-endpoint="https://events.wefido.it/v1/events"
  data-wefido-auto-pageview="false"
  defer>
</script>

WefidoSignals.setConsent({
  granted: true,
  version: "cmp-policy-2026-07",
  recordedAt: new Date().toISOString()
})

WefidoSignals.track("lead", { form: "contact-request" })

WordPress

Guided installation and CMP support

The plugin integrates with the WordPress Consent API, CookieYes, Complianz, Cookiebot, OneTrust, iubenda and Borlabs Cookie. Events are sent only when the required consent can be verified.

Install the ZIP from Plugins > Add Plugin.
Open Settings > Wefido Signals.
Enter the source public key, purpose and consent version.
Verify the domain and inspect diagnostics.

Keep the same event_id across retries: duplicate requests are not counted twice.

Server-to-server conversions

The secret key always stays on your server. After activating the source, you will receive the credentials and instructions required to sign each request.

// Keep the secret key in your backend only.
// Use the source credentials to sign every request.
